■shaken, and more or less valueless. This remark is not only applicable here, hut also 

 in various other sandstone quarries, where the character of the stone is spoilt by the 

 mode of raising the blocks.] 



All the stones are free-working, and, if raised with care, and 

 well-selected, are durable. Formerly they were very extensively 

 used in Belfast, but of late years they have been cut out by a very 

 general introduction of Scotch stone. 



These quarries also supply good strong flags, from 2 '5 to 3 in. 

 thick. 



Newtownards is built nearly solely from these quarries ; the 

 large Town Hall, as pointed out by Wilkinson, displaying some 

 .good work. 



The Scrabo stones have been used in Belfast, in the Albert 

 Memorial, St. Enoch, Fortwilliam, Sinclair's, Elmwood, and 

 Donegal-street churches ; the Academy, in the offices of Eobinson 

 and Hewits, and the warehouse of Eobinson and Cleaver, the last 

 two being from the Glebe Quarry. They were also used in Stor- 

 mount Castle and the Model School and Strain Church, New- 

 townards. Mr. William Gray, M.E.I.A., says of the stone, that 

 it is " very variable in colour and texture, stands fairly well 

 when selected and set on bed, but tilted on edge it will not stand. 

 It works freely, and, as a rule, is of a light-brown colour." And 

 of the " Glebe Quarry " :— " It yields a light-coloured stone, of 

 very even texture, and good colour. It is soft, but stands fairly 

 well, and makes a good building stone. 



Dundonald. Four miles from Comber : — Eed ; fine-grained ; 

 like the Dumfries stone (Scotch), and has been used for it. The 

 quarry does not yield a very large quantity. Has been used in 

 Belfast in the Spencer basin ; cottages and villas at Knock ; Preston, 

 Smith & Co.'s Warehouse, &c. ( William Gray.) 



The principal Irish sandstones used in Belfast are from 

 the Scrabo and Dundonald quarries, Co. Down; Dungiven, Co. 

 Londonderry ; Ballycastle, Co. Antrim ; Cookstown, and different 

 quarries near Dungannon, Co. Tyrone ; those from Eanfurly, 

 Mullaganagh, Bloomhill, and Carlan being most preferred. 



Sand and Gravel. — Good pit sand occurs in the valley of the 

 Bann, also at Saul, between three and four miles from Down- 

 patrick, in the neighbourhood of Newtownards, and in other places. 

 There is good river sand in various places along the streams and
